Summary: When the UIViewControllerTransitioningDelegate method - presentationControllerForPresentedViewController:presentingViewController:sourceViewController: is called, the presenting view controller is unexpectedly nil. Steps to Reproduce: 1. Open the attached sample project, which implements presentationControllerForPresentedViewController:presentingViewController:sourceViewController: and asserts all the arguments are non-nil 2. Run it 3. Tap to present a view controller Expected Results: For no assertion to fail. I.e. for presented, presenting, and source to to non-nil, as they are documented as nonnull. Actual Results: presenting is nil. Version: iOS 9 beta 5 Notes: Workaround: the source is often good enough so we are currently basing decisions about what presentation controller to return by querying `presenting ?: source`.
